I have a few Winston BIIx and BIIIx 4 weights. I bought the BIIIx this year in 8'6" (4) weight and believe its one of the greatest rods made. The BIIx in the same weight and length is also great but the BIIIx is a bit stiffer in the butt section which equals more casting power with less effort. I would not hesitate a BIIIx purchase. Plenty of power and you can cast dries and weighted flies with this rod all day long. The 8'0 Winston BIIx is also a gem for smaller dry fly work.

Well I had the opportunity to play with the Biiix in a 9 ft 4 wt over the weekend and loved it. I think it'll be a great dry fly rod that can also handle small nymph work and some streamer work. I broke down and got one. Figured i'd post this here given that I was the OP in this thread.
